BLOOD TESTS
SERUM CORTISOL
Cortisol is a hormone produced by your adrenal glands. And its function is to help your body respond to stress. It also plays a vital role in regulating various functions, such as metabolism and immune response. Measuring serum cortisol levels can provide valuable information about the health and function of the adrenal glands and offer insights into a variety of health conditions.
Why Is A Cortisol Blood Test Important?
A serum cortisol test helps diagnose conditions that affect cortisol production (the “stress” hormone). Low cortisol may suggest adrenal insufficiency or Addison’s disease, which can lead to fatigue, muscle weakness, and weight loss. High cortisol might point to Cushing's syndrome, associated with symptoms like weight gain, high blood pressure, and elevated blood sugar levels.
Understanding Your Cortisol Blood Test Results
Serum cortisol levels are usually measured in micrograms per deciliter (µg/dL) or nanomoles per litre (nmol/L). Serum cortisol levels can also naturally fluctuate throughout the day, generally peaking in the morning and tapering off by evening. However, a typical reference range for serum cortisol is approximately 10-20 µg/dL (micrograms per deciliter) in the morning and 3-10 µg/dL in the afternoon.
Core Blood Markers
The Prostate-Specific Antigen (PSA) test primarily measures the level of PSA, a protein produced by the prostate gland. The core biomarker for this test is PSA itself. Elevated PSA levels can indicate prostate issues, including benign prostate conditions, infections, or prostate cancer.
However, the PSA test is not specific to cancer and requires further investigation for an accurate diagnosis. Normal ranges can vary based on the time of day and testing method. Morning levels (when cortisol is at its peak) are often between 5 – 25 µg/dL (138 – 690 nmol/L). In the evening, levels typically decrease significantly due to cortisol’s diurnal rhythm.

Many doctors recommend a morning test (around 8 - 9 am) to obtain baseline levels, but a second test may be done in the afternoon to observe fluctuations.
